How to play

The idea

Most players are Good and want three quests to succeed. A hidden few are Evil and want three quests to fail. Evil players usually know each other. Good players have to work out who to trust from how people talk, vote and act.

Each round

The leader picks a team of the size shown on the next quest seal. Everyone discusses, then everyone votes in secret. If more than half approve, the team goes on the quest. A tie, or anything less, rejects the team and leadership moves to the next player.

On a quest

Each team member secretly plays Success or Fail. Good players can only play Success. Evil players may play either. The cards are shuffled, so you only learn how many Fails were played. One Fail ruins the quest, except the fourth quest in games of seven or more, which needs two.

Ways to win

Evil wins at once if three quests fail, or if five teams in a row are rejected. If three quests succeed, the Assassin gets one guess at who Merlin is. A correct guess steals the win for Evil. A wrong one means Good wins.

The roles

• Merlin Good

  You know most of the traitors.

• Percival Good

  You can see who might be Merlin.

• Loyal Servant Good

  You know nothing for certain.

• Assassin Evil

  You serve Evil, and you hold the final blade.

• Minion of Evil Evil

  You serve Evil alongside your allies.

• Morgana Evil

  You serve Evil, and Percival may mistake you for Merlin.

Merlin and the Assassin are always in the game. Percival, Morgana, Mordred and Oberon are optional and chosen by the host.

Table manners

Talk as much as you like and say anything, but never show your screen. Hold your phone close during the secret reveals.
